Radio relay appliance activation

Abstract

Remote appliance activation can be achieved by relaying between radio frequency transmission schemes having different characteristics. A radio receiver receives radio frequency control signals for controlling the appliance. Each existing radio frequency transmitter is specifically designed to transmit wireless radio frequency control signals having receiver characteristics to the radio receiver. A new wireless radio frequency transmitter has transmitter characteristics, at least one of which is different from receiver characteristics. A radio relay learns the receiver characteristics from one of the existing transmitters and learns at least one transmitter characteristic from the new transmitter. Then, when an appliance radio frequency activation command is received from the new transmitter, the radio relay transmits a new radio frequency appliance activation command having the learned receiver characteristics.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to remote control of appliances such as, for example, garage door openers.[0003]2. Background Art[0004]Home appliances, such as garage door openers, security gates, home alarms, lighting, and the like, may conveniently be operated from a remote control. Typically, the remote control is purchased together with the appliance. The remote control transmits a radio frequency activation signal which is recognized by a receiver associated with the appliance. Aftermarket remote controls are gaining in popularity as such devices can offer functionality different from the original equipment remote control. Such functionality includes decreased size, multiple appliance interoperability, increased performance, and the like. Aftermarket controllers are also purchased to replace lost or damaged controllers or to simply provide another remote control for accessing the appliance. An example application for...

AI Technical Summary

Benefits of technology

The present invention provides a relay between different radio frequency transmission schemes with different characteristics. This allows for the control of an appliance using wireless radio signals with different characteristics. The invention also includes a system for controlling an appliance using a fixed code or a rolling code, and a method for controlling multiple appliances using different radio frequency signals. The invention also includes a universal garage door opener that can operate multiple radio frequency devices and a second transmitter for transmitting signals through AC wiring. The technical effects of the invention include improved control of appliances using wireless signals and increased flexibility in the use of different radio frequency devices.

Problems solved by technology

One problem with such devices is the need to put a complex electronic device within the vehicle, where space is a premium.

Another problem with such devices is the requirement that they operate together with existing remote controls.

Yet another problem is the difficulty experienced by users programming such devices to work with existing garage door opener receivers.

Such installation is beyond the capabilities of some users.
